Looked at it. I found it rather enjoyable. While the message is somewhat predicatable, that didn't really stop me from enjoying it. I think a more twist-y direction that you could take with it is that the narrator is actually the one who caused the drunk driving incident, but still gets to come back as some punishment for it so he has to deal with his "downfall" of it, but that's more of a darker turn for it that i don't really seem as necessary, just something to think about.
I think this is a good story, again, and pretty impressive for your first post, here's just some nitpicks:
1. I think the language gets a bit repetative, and there's a lot of just saying the same thing over and over in different ways.
"All there was, was me falling, falling, falling away from it all, into an endless expanse of black nothingness."
". I floated and I floated, going nowhere and yet seemingly being everywhere. "
I would switch up some of the language here to make it seem less repetative while keeping the language intact.
2. "I fucking hate blue jeans. " I find it funny and kind of strange that the main character seems more upset about blue jeans than dying
3. "You worked as a cashier at a grocery store. " This seems as kind of a strange thing to put into here in the middle of everything else, as it's not that remarkable
overall I liked the text and I want to see more, but I just think it needs a few tweaks to get it fully complete. Good work!
